Queenie's 55 Effie ... Diary of an F100 Project
OK ... I got the "Electric Choke" working correctly ... required some delicate fabrication using "Mis-Matched Parts" a welder, grinder and a hacksaw ... no small feat, but it works as intended and I did it for five bucks.
I think I'll get a factory style "Cold Air Intake/Air Cleaner" fixed up for the old girl before I pack her away to make time for the Camaro projects and the Mach1 Tach replacement.
THERE IS A STORY BEHIND THIS CHOKE ... HERE GOES ... COPY from "Garage" forum
This is mostly just another dumb story flowing from the fingers of Larry (that's me)
I got the wiring pretty well wrapped up on the Effie and wanted to get an electric choke on the Carb ...
The carb runs quite well not to mention it's been around a long time, helk it's almost a part of he family ... and right now I have no desire to spend more $$$ on another carb or any prefab choke set-up ...
So I resorted to my usual technique ... JUNKYARD scrounging.
Just so you know this carb is a Rochester QuadraJet (which is what I run on everything)
It came with one of those hot-air type chokes and I mangled that into a "manual pull" when I moved it from the Mach1 to the Camaro years ago.
For now the Carb is a "Dufer" on the 460 on the Effie Project.
I went to the salvage yard the day 545Mike was here and we found some basic componenets and came home.
The problem is ... in doing that you invariable end up with a "Mis-Match" of parts ...
Well after Ross and Mike helped me get the stuff mounted up ... I spent two days messing with things trying to figure how they should work ...
Then an epiphany hit me ... I finally quit thinking about "how the mechanism worked" and more about what the choke HAD to do.
It occurred to me:
It has to "Set the Choke" meaning "Close the Butterfly" up top and set the "Fast Idle."
It then had to allow the butterfly up top to open when it was ready to ... and do so independent of the fast Idle.
Then the fast idle "MUST" shut off once the throttle is punched.
AND ... this must all happen ... with no parts binding or ever interferring with other functions.
Once I got that understanding under my belt, I could look at my "Mis-Match" parts and figure out "what to do to them" to make all that happen.
Anyway, between the grinder the hacksaw and the welder ... I think I have now fabricated a functional electric choke, out of a pile of mis-match parts ...
And that is the end of my "DUMB STORY"
Moral to the story may be just as Ross told me a few days ago ... Sometimes one can end up with so much information you can't even think it through anymore ... It just becomes more and more confusing
When in Doubt ... SIMPLIFY
BTW ... Those are some damn tiny parts to be grinding and welding on.
NEXT PORTION ...
I got off work and decided to test out that newly fabricated choke ...
I had to do some bending on the rod between the choke lever and the butterfly to shorten it a tad (this was not allowing the Choke Lever and Hammer to fall far enough in the "off" position to un-lock the secondaries) ... I also had to grind down my Fast Idle pad on the mechanism I fabricated (I couldn't turn the fast idle down low enough with the adjuster screw)
Once I got those two things set up right ... all was well ... Choke sets and so does fast idle, the butterfly slowly opens to allow leaner mixture once the engine is running and beginning to warm up ... and the fast idle shuts off with a punch of the throttle ...
Gotta-Love-It ... It's so fuss free even Queenie will be able to deal with it
